Pair annihilation of weakly interacting massive particle (WIMP) dark matter into high energy photons taking place in dark matter halos at all redshifts might contribute to the extragalactic diffuse gamma-ray radiation. The γ- annihilation channel would give rise to a distinct feature in the spectrum, a line which is distorted by the integration over all cosmological redshifts. We present a study of GLAST sensitivity to detect an extragalactic signal from a generic, thermal WIMP with a continuous spectrum part, modeled with annihilations into bb̄, and a γ-line, from the 2γ final state.
